TextTrigger string display problem

[sean.e]

The TextTrigger string display gets a bit corrupted in certain cases.  Here is an example:

HEADM adc 2 2 adc-null adc-null Empty Empty 1 menupage-obj ;=0,0,100,0
TEXTTRIGGER texttrigger 2 0 "trigger: 0" "trigger: 1" ;=125,75,100,0
MENUPAGE menupage menupage menupage 1 texttrigger-obj ;=275,75,100,0

If you remove the colons from the strings, then they are displayed as expected.  Also, the last value is not affected.  So if there is only one value, it will work as expected.

Should have noted that the problem is on the H8000A OS 5.2 rather than in Vsig.

The problem is not specifically related to the semi-colon.  Here is another example:

HEADM adc 2 2 adc-null adc-null Empty Empty 1 menupage-obj ;=0,0,100,0
MENUPAGE menupage menupage menupage 1 OptionTextTrigger-obj ;=525,500,100,0
C_MERGE SwitchCntResetMerge 2 SwitchSelectCounter-timeout 0 ;=125,100,100,0
C_MERGE SwitchCntIncrMerge 2 SwitchCntResetMerge-out OptionTextTrigger-out ;=125,225,100,0
C_COUNTER SwitchSelectCounter SwitchCntIncrMerge-out SwitchCntResetMerge-out 1 3 ;=275,350,100,0
TEXTTRIGGER OptionTextTrigger 4 SwitchSelectCounter-out "default off" "option 1 ON" "option 2 ON" "option 3 ON" ;=125,475,100,0

The corruption is due to the length the of trigger text.  If an item has more than 9 letters, its display is truncated and the text from the next item is partially concatenated to it – displaying up to 16 characters (even when the original text is less than 16 characters).  The truncation doesn't occur if the item text is 9 characters or less.  The concatenation of the next item to the current item likewise doesn't occur if the current item is 9 characters or less.

I wrote to support noting that this problem is not addressed in OS5.5B and added this information:

The TextTrigger has 4 values:

default off

option 1 ON

option 2 ON

option 3 ON

The H8000 displays these values:

default ofoption

option 1 Ooption

option 2 Ooption

option 3 ON

nick:

i) Vsig
correctly displays a maximum length of 10 chars for this field, but then
allows you to enter 11.

ii) The H8000 should allow a 10-char value with no terminator, but seems
to demand a terminator, which is why it runs into the next field.

So far as I can tell, there is no
indication in VSig that the max length is 10 characters.  VSig displays
the text properly in the specifier display  The text type Max column is blank. 
The Min column has length.  It does show that the maximum number of
strings is 10 (nstrings).

In the Vsig specifier display, beside each text line (e.g. text1, text2) you will see the word length (Min column) followed by the number 10 (Max column).  This means that the maximum length of these text values is 10.

But, the bug is that this 10 includes a terminator, so the number of characters is actually 9.

Weird – my 2.5 version of Vsig has a blank max:

[sean.e]

Just checked 2.4.9.0 and it works properly there.  Not sure why I was using 2.5.0…

[sean.e]

Just tried Get Dbase using 2.4.9 with OS5.5B but it still reports Unknown Field Type – Database is corrupt.

[sean.e]

now I remember – I had 2.5 to test out a Vista compatibility bug.

This looks like a new bug (sorry) – it's on the list. In the meantime, keep using the V5.3 database.
